Peter you just gave me a great idea, when boring soft jaw on 3 jaws chuck, you can bore the ring as the jaw, than you can inspect diameter with a dial bore, no need for three point mic!

I ran a super long run full sheet this morning and got half way through and realized I'd goofed it. Your constant reminders to check these things because of valuable parts has made me much more conservative in my word but resulted in way less dumpster parts.
You are one of my machining fathers. I started very late in life. About 1 year ago and Im 36 now and I learn so much from You high level RUclips machinists.
I really want to move into this type of machining. It's so much more engaging and involved than what I do with Wire EDM machining Tungsten Carbide. Every now and then we get something different that actually requires some thought of how to hold it, the direction and order of the tool paths etc. The vast majority of the time it's just rinse/repeat churning out hundreds of the same thing. Oh look, it's another hole that needs to be made bigger 300 times🙄
I always debur my jaws very good and large right after roughing so when i finish turn the jaws are absolut smooth and i dont have problems with runout on a 3 jaw from taking it out and putting it back in after deburriung (if i hade dirt in the tooth or somthing)
Hey Peter, sorry to hear about the problems with your arm. While I was watching, I thought maybe it would be possible to tighten the jaws with a torque wrench as a final op. Probably totally overkill in this application (and also increasing the setup time), but the advantage might be that the ring would be deformed more symmetrically (it seemed to move quite a bit when you released the jaw pressure), and also when you put the final part in then the jaw deformation would be the same. As I say, for the time taken, probably not worth the effort, but got me thinking !
Could you use a much larger disk where you milled the center hole and then four slots for the pins? That would reduce the amount of deformation essentially to zero.
I'm sorry to hear that you're having trouble with your arm. Have you talked to a doctor about what you could do about it while still being able to do your job?
Just to add some context to non-machinists. I can't skip not boring soft jaws on 2nd lathe operation because if i don't do that then the Runout between both surfaces will be anywhere from 0.2 mm to 0.4 mm or more (3 jaw chuck). If i bore the jaws i can get the runout down to 0.015-0.07 mm easily and that's good enough for most parts which require about 0.1 mm of runout. So it's not skill or patience or "doing the job right" but an absolutely necessary step that you can't skip.
They want me to machine the parts I started to the new revision on the second end. I don’t have to change anything I have already done. So that’s good!
On a solid part I put almost as tight as I can with my 3/4” ratchet wrench fully extended to about 30” long. On very large parts I even put a cheater pipe on that. So what ever that torque is I don’t know.

I don't believe there would be a way for the machine to know where your jaws are set. or the center of mass for each individual jaw. If it did do this, it could also cause a crush problem on the part you might be working with. There are so many variables to what you could be doing, I'm not certain this would be beneficial to the point that someone has developed it.

Can’t unhide the menu bar on the Mazak control. If you do, you can’t operate the controls soft keys. It covers them. The mouse pad on the controls panel is very hard to use.

Hi Peter Why not , instead of just using a piece of pipe unfinished, go ahead and turn a piece that is turned to tolerance to keep and use again in your setups ? It seems like you would be a little closer to begin with. I understand that you don't have to cut soft jaws very often but seems like it would be about the same time to have a finished ring ready for next time. Maybe I missed something because I am replying while watching so sorry in advance if so
That certainly could be done. Right before making this video. I found this. Piece of pipe in the drops by the saws here. I just used it as is. I could and should of just indicated over the tops of the pins in the chuck jaws. Then it doesn’t matter how rough the ring is.
In the case of this chuck, it is a 4-Jaw chuck. So it has no scroll of course. But on the 3- jaw I’m generally changing the chucking diameter so it is changing position on the scroll unless just by accident it lands in the same spot.
If you watch around the 3:00 mark, the spindle locking mechanism doesn't appear to be actuating smoothly. Might be something to keep an eye on. I'm conflicted: really want to see a teardown of that head, but I also wouldn't wish a spindle rebuild on anyone.
i have watched it 5 times and i dont see anything wrong. I only see the reflection on the inner side chamfer of the spindle, is that what you are referring to?
I also don’t know what he is referring to. I am orienting the spindle manually. Than locking it. He can’t even tell when it locks/clamps. He only knows because I said it. You can’t see it happen. The Capto spindle isn’t a round taper. So when it orients it may look different than you are useto.
At 3:05, there's movement in the reflection of the Capto holder just before you insert the tool. I suppose I should have said Capto lock as there is also the spindle rotation lock.
@@ipadize Not sure, I haven't used a Capto setup before, the sticking I'm used to is the bar unseating the taper (CAT 30/40 tooling). It all happens in a few frames of the video so it's hard to tell, for all I know that's just how the Capto mechanism works. On a side thought, is the Capto release pneumatic or hydraulic on the Integrex?
Why in the first place do you machine your jaws in a 4 jaws chuck? In anyway they don't keep any repeatability if you want to change parts. I saw you individually adjust the jaws before cutting the part so why you put the effort and machine the jaws?
In these cases I bore the soft jaws to hold the part more securely without marring the finish. If I were to grab the part in the hard jaws even with packing to help prevent damage. It is more difficult to indicate in the part. With bored jaws you only have to indicate the runout at the chuck. But the other way you have to make sure your runout is good at the chuck than out at the end back and forth. Because I don't have a turned area to indicate out at the end boring the jaws assures everything is running true along the entire length of the part. If you watched the video on the first operation. In that video I just used the hard jaws.
Peter; Iove you to death and have nothing but respect for your knowledge. But as a Mazak Integrex machinist myself I have to question the setup with a manual chuck. In our daily operations we do a lot of single parts and we use hydraulic chuck with hardened jaws with aggresive tooths for first operation (with added bonus of being able to take the part down and back up with near zero runout
@Yeah Right Mazatrol is not just for the 80's and 90's. It is one of the most powerful turning CAM systems that are out there. I have programmed from Mastercam, Hypermill, G-Code and Mazatrol. Maztrol programs are typically faster and easier. It does havesome special rules, (as all CAM software does.) However, the amount of control a machinist has at the control means better optimized programs, as well as faster programming times. Typically lead to a faster product. I wouldn't use it for a mill or even a turn/mill. But it is seriously powerful on a 2x lathe.
If you watch Peter's other videos, you will see he does a mix of oddball parts and not all of them are round. The 4-jaw works for his situation even though it takes time to indicate every part. The 4-jaw also gives him maximum spindle bore use vs a hydraulic chuck with a draw tube reducing the bore capacity.
I'm sorry, Peter. I know you like esprit, but that tool offset feature is despicable. A tool offset number should be in the tool settings, not the toolpath. Its too rare to have different offset numbers than to have to remember this feature every time.

Do you ever apply 'undercuts' when cutting jaws? If so then how would you recommend doing it and with what type of cutter? Thank you for your videos.
This part has a step in the end. So it doesn’t need any undercut. But I do do that if necessary. Usually with a VNMG inserted bar.
I just came across a situation needing to do this for smaller 3 soft jaws but I am wondering if I can do something similar.....Hmmmmm!
When you say they changed the design is that for future parts or do you have to rework any that you already have in-process?
They want me to machine the parts I started to the new revision on the second end. I don’t have to change anything I have already done. So that’s good!

Excuse me sir is there any list of videos for the beginners of 5-axis m/c?
if you are gripping the jaws at the front, do you also need to turn at a slight taper? Like you usually have to do with jaws that long ?
If I can support the jaws for boring this way. I turn them with no taper.
